Enhancement: Improve Code Readability and Error Handling in vote_weight_record! Macro

[techvoyagerX]

Summary

The vote_weight_record! macro in spl/src/governance.rs provides a wrapper for the SPL governance program's VoterWeightRecord. While it is functional, there are opportunities to improve its code readability, error handling, and overall maintainability.

Proposed Changes

1. Error Handling:

   • Ensure consistent error messages.
   • Add clarity to the reasons for deserialization or serialization failures.

2. Code Readability:

   • Add type annotations in complex deserialization logic for better understanding.
   • Improve comments to explain the purpose and functionality of key components.

3. Documentation:

   • Provide comprehensive comments explaining feature-specific configurations (e.g., idl-build).

4. Consistency:

   • Standardize logic across all implementations (e.g., deserialization with and without initialization checks).

Benefits

• Enhanced maintainability of the code.
• Easier for contributors to understand and modify the macro.
• Improved debugging experience due to clearer error messages.
